The ascetic believes faith and devotion are best expressed through denial of bodily needs.
Ascetics temper their flesh and their wills with physical deprivation and rituals meant to inure them to pain and gain complete control of their physical form. The extreme testing often breaks lesser creatures, but those who endure it can achieve a level of physical resiliency and perfection that is almost supernatural.
An ascetic is not proficient with any type of armor or shields.
6 + Int modifier.
The ascetic gains Toughness as a bonus feat at 1st level. At every even level, she may select a bonus feat from the following list: Acrobatics, Agile Maneuvers, Alertness, Athletic, Blind-Fight, Combat Casting, Combat Expertise, Combat Reflexes, Dodge, Defensive Combat Training, Diehard, Endurance, Fleet, Great Fortitude, Improved Initiative, Iron Will, Lightning Reflexes, Lunge, Nimble Moves, Run, Self-Sufficient, Skill Focus, and Toughness. She must meet the prerequisites for these feats.
An ascetic does not gain the ability to spontaneously cast cure or inflict spells by sacrificing prepared spells.
However, she can spontaneously cast the following spells by sacrificing a prepared spell of the noted level or above. As an additional limitation, only the ascetic can be the target of these spells.
1st level—endure elements
2nd level—bear’s endurance
7th level—ethereal jaunt
8th level—iron body
9th level—astral projection
She may divide the bonuses in any way between these three ability scores. She can change the distribution of these bonuses when she prepares spells.
When unarmored, an ascetic adds her Wisdom bonus (if any) to her AC and her CMD. These bonuses apply to AC even against touch attacks or when the ascetic is flat-footed. She loses these bonuses when she is immobilized or helpless, when she wears any armor, or when she carries a shield.
